AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 603 AM CDT Sun Jul 12 2020
Discussion. Issued at 346 AM CDT SUN JUL 12 2020
After a couple of stormy nights for some, the synoptic high pressure situated in the southwest US pushes a little further northeast. This will guide any storms further north keeping them away from EAX for a few days. This break from storms would normally allow heat to build in the area. However, the mesoscale complexes which affected central NE through south KS/MO and OK have disrupted the Gulf moisture flow. This coupled with northerly mid to upper level winds will keep temperatures and, most importantly, dew points from being uncomfortably high.
Monday, the Gulf moisture channel begins to reestablish itself in western KS. By Tuesday, that channel shifts east allowing heat and humidity to build with temperatures ranging from 90F-95F and dew points in the low to mid 70s. Do not fear, as a leeward low develops off the Rocky Mountains in western OK and sets a warm front up across EAX through the afternoon and overnight Wednesday. Those north of the front will see temperatures in the mid to upper 80s whereas those south of the front will crest 90F. While these temperature discrepancies may not seem fair for those soaking in the heat, the warm front does bring the opportunity for some much needed rain across the area overnight.
Unfortunately in conjunction with the surface low moving in from the west, the surface high pressure located in the SE US is pushed further east redirecting hot, muggy air directly into EAX as daytime highs on Thursday reach well into the 90s with dewpoint clearing 70F. These conditions are expected to persist through next weekend.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
